Our students taught a class on the mechanics behind pulleys, how pulleys can be used to lift weights, and how to construct them. 

They finished with building one with 6 pulleys on the basketball court,  It turned out to be strong enough to be used to lift up a child, or a thin university student. You only need one-sixth of the force.  Everyone wanted to be lifted up on it.
